FEATURES
Isolated Hermetic Package, JEDEC TO-257AA Outline
Output Voltages: -5V, -12V, -15V
Output Voltages Set Internally to ±1%
Built-In Thermal Overload Protection
Short Circuit Current Limiting
Product Is Also Available In Non-Isolated Package
Similar To Industry Standards 7905, 7912, 7915
DESCRIPTION
These three terminal negative regulators are supplied in a hermetically sealed metall
package whose outline is similar to the industry standard TO-220 plastic package. All
protective features are designed into the circuit, including thermal shutdown, current limiting
and safe-area control. With heat sinking, they can deliver over 1.5 amps of output current.
These units feature internally trimmed output voltages to ±1% of nominal voltage.
Standard voltages are -5V, -12V, -15V. These units are ideally suited for Military
applications where a hermetically sealed package is required.
